注释:
1、 句中谓语动词tells 的宾语有两部分组成。 第一部分是when to form flowers, 是带疑问浮词的动词不定式,第二部分是when the flowers should open, 是名词从句。从修辞上说,两者有些不平衡。
2、 …the way we do our work 可以理解为the way in which we do our work 或the way that we do our work. 实际上,三种说法都成立。如:He speaks English the way the English people do. I don’t understand the way in which he dealt with the matter.
3、 take 作“花费,花去”解时可用于几种不同的句型:
It will take me five days to complete the work.
The work will take me five days to complete.
To complete this work will take me five days.
